I think he is talking about the one in the 2.5 alpha.
Pov Ray dosen’t have a GUI. You hand code your objects, lights and effects into a text editor. Honest! A freind of mine used to do it and got some decent results.
There are a few front ends and exporters. One is built into 2.5, but it gives strange results.
Pov Ray dates back to the 80s. Yes, the '80s. Before Guis, before the dark times, before the empire, there was Pov Ray.
While you CAN do everything manually, you don’t HAVE to.
There are loads of more-or-less capable front-ends although admittedly, they are all getting rather long in the tooth…
The web is filled with Povray resource, tutorials, material generators, include files (helper programs) etc etc
While not quite up to todays standards (but still powerfull nonetheless), Povray is still loads of fun to discover for someone interested in computer graphics.
povray/blender render integration I wrote as a reference for other people to use, if you look in the render panel povray radiosity settings are supported. Blenders metaballs export to povray correctly. area lights also. So its not totally useless but its more of a test that blender2.5 can even work with an external rendering engine.
Some comments here seem to miss the point of blender/povray integration, The idea is that blender IS the GUI to pov (a frontend at least).
On Linux it should be as simple as installing Povray from the package manager, then running blender, selecting povray output and pressing render.
